Harvel® HydroKing® Commercial CPVC piping is routinely tested for strength and durability as well as conformance to national standards through rigorous quality assurance testing. This includes testing by independent agencies to verify the product’s quality and safety. Stringent testing is conducted by NSF International (NSF) to ensure that Harvel pipe meets the requirements of NSF Standard 14 and NSF Standard 61 for quality and health effects. Additional physical performance testing ensures that HydroKing® pipe does not contain nor contribute any harmful substances to transported drinking water. As a result, HydroKing® pipe bears the NSF stamp of approval for potable water applications. Based on large scale testing, Harvel® HydroKing® is also Listed for Surface Burning Characteristics by ULC having a low flame spread rating (<25) and a low smoke development rating (<50) validating the excellent fire performance properties of the piping. This Listing can be used to validate that Harvel HydroKing® can be installed within return air plenums based on its excellent fire performance properties. Harvel HydroKing® also meets CSA B137.6 Chlorinated Poly(Vinyl Chloride) (CPVC) pipe, tubing, and fittings for hot and cold-water distribution systems – this information, along with ULC flame and smoke information is printed on the pipe for easy identification in the field.
